The agency carried out #Trump’s directive, which came in the wake of catastrophic #wildfires in #LosAngelesCounty, on short notice on Jan 30, though it would normally require days to coordinate. A memo written 4 days after the release, obtained by The Post through a public records request, shows how federal ofcls rushed ahead w/the plan to release #irrigation #water despite objections from #California’s elected ofcls & local #farmers.

“If there's no funding," Bart Fisher, who sits on the board of the Palo Verde #Irrigation District in #California said, "there will be no #conservation."

#Farmers in Palo Verde use #ColoradoRiver #water to grow #cattle feed & #vegetables in the desert along the Arizona border. Fisher said they want to be active participants in protecting the river, but they stand to lose money if they use less water & grow fewer crops.

Pottery by Osa

Olla update: I’ve had my #garden ollas in place for 2 weeks now and they are still half to 2/3 full of water. The seedlings around them have grown steadily. We’ve had light rain once in the last two weeks. The true test will be when temperatures start to soar, but so far this #irrigation method has been impressively easy & efficient. It’s wild to know that an #ancienttechnology can still be so useful and relevant. I love clay! #pottery #ceramics #keramik #permaculture #gardening #ollasbyosa

Two terracotta pots with lids. The one on the left is larger than the one on the right. They both are curved forms with a narrower neck decorated with textured rings. Each has a lid that features carved geometric pattern decoration. The background is plain, sage green.

Holding a hose.

Yesterday, faced with a problem of irrigation control and connectivity, I wondered:

Has anyone produced a data transmission interface that works for water-filled irrigation pipes?

Googling, I see a slew of articles referring to the 'garden hose analogy for bandwidth' but vanishingly few (so far) references to using actual garden hoses as data link layers.

I am suggesting, and referring in whatever future this idea has, to :

#pppp #fourP, or #4P
The Plastic Pipe Packet Protocol.

(Hope that's OK with you.) (I see it is already-used for "Piss Poor Prior Planning", which seems decidedly apt.)

[takes me back to my engineering geology days in the Southern Hemisphere, including my thesis – with a healthy dose of spatial analysis and modeling – and all with a specific use; what is not to like?]

photos - (A) The main fluvial landforms in the AOI. The Carumas river can be seen here to be bounded by landslides affecting a fluvial terrace covered by agricultural terraces. (B) Landslides affecting a slope close to a community in the AOI. Note the construction of terraces on prior landslide deposits.
schematic / cross-section - Typical profile of terraces built in Southern Peru. Wall rocks are directly piled over an excavated trench in bedrock without mortar. An upward decreasing gradation is used to fill the internal portion of the wall in compacted layers. Fertile arable soil is placed in the top 30 cm.

Q-pl = colluvial deposits, debris avalanche. Qp-vl-pi = pyroclastic deposits. Red line marks the topographic cross-section shown in A. (C) Cross-section of the San Cristobal landslide with estimated base groundwater conditions (blue) and materials boundaries (green) to be used for modeling and interpreted potential failure surfaces (dashed red).

a Time series of near-global (60° S–70° N) mean SST anomalies, Niño 3.4 (black), the Pacific Decadal Oscillation (PDO) index with 1-year smoothing (blue), and a North Atlantic tripole index (brown). Negative PDO corresponds to anomalous positive SSTs in the central N. Pacific. b Near-global ERA5 SST trend, 1980–2022, °C/yr. c Correlation between the Niño 3.4 index and GRACE/FO d(TWS)/dt, the latter lagged 2 months with 4-month smoothing applied. d Correlation between the PDO index and GRACE/FO TWS, 3-month smoothing applied
Map of mascons in which the GRACE/FO era minimum terrestrial water storage occurred after the start of 2015, color coded for the year of that minimum. The time series plotted in Fig. 2 is averaged over the South American region delineated in red
Comparison of ERA5-Land, GRACE/FO, and complementary observations: a deseasonalized time series of global land average (60S-70N) TWS anomalies (mm) from GRACE/FO, ERA5-Land, and ERA5 vertically integrated moisture flux convergence, b ERA5-Land precipitation (P), evapotranspiration (ET), and runoff (RO), c same as b but for GPCP P, GLEAM ET and G-RUN RO. Units in b and c are mm d−1, d 2003–2022 trend in ERA5-Land P-ET, e Same as d but for GPCP v3.2 P—GLEAM 3.6a ET. Units in d and e are mm d−1/yr. All anomalies are relative to the 2003–2022 monthly resolved climatological mean
TWS trends (mm/yr) over the period 2003–2022 in a GRACE/FO and b ERA5-Land; and c correlations of monthly TWS anomalies between GRACE/FO and ERA5-Land. Ice sheets and areas of significant glacial extent have been masked
